Even world leaders can't resist taking funeral selfies. President Barack Obama, Britain's Prime Minister David Cameron and Denmark's Prime Minister Helle Thorning Schmidt can be seen in the photo taking a selfie during a memorial service for Nelson Mandela on Tuesday.

What photo sharing network would be complete without Vice President Joe Biden? The answer is none, which makes Instagram the first network to qualify. The vice president signed up and posted his first image, though the first pic is actually from his Office staff and not Biden himself.
